Lens Shift-Digital Projectors

The Lens Shift feature of a projector allows the optical lens to be physically shifted up and down (Vertical) or left and right (Horizontal) to get images appear in right way from varied locations. Lens shift feature is better than Digital Keystone Correction because in keystone correction images are adjusted digitally which results in degradation or distortion of images but in lens shift quality of images remains unchanged. It also gives freedom in placing projector anywhere.
